also, the black box x-ray. not sure about that one. stevekim had that one for a lil while (along with every other frickin distortion unit ever made!). not sure if he liked it. it costs a few more than the angler.

then there's the "boutique" stuff like z-vex. but that'll be more than a mim fender, iirc.

I'm one of the few that would recommend a multi-fx unit. I had the BFX708, and it was poo really. I've just got a GT6B, and it pees all over it.
It has got about 7 dist model, including the main Boss ones (Metal Zone, ODB3, Turbo overdrive etc), which to my ears are dead ringers. It also has a Marshall Guv, Big Muff, which sounds gorgeous and a couple of others.
You also get 6 amp models, which you can overdrive to get tube type dist.
